Why shouldn’t I buy a unit that covers just part of my property?

Covering just your bed, for example, is a big improvement to your body, but covering the whole property is of much greater benefit because you are feeling the benefits of the beneficial energy field from the unit for the whole time that you are in that property. Conversly, if a unit only covers part of a property you are going in and out of GS and the effects of ES as you go around the property, which is definitely not as beneficial for the human body, as it would be with the whole property covered.
